Got 2 new toys, cant get info.

[Cruiseomatic]

Thanks. Where can I find service info or literature on these two? I saw them today and the temptation to power them up is strong but didn't. Especially since the only a/c I can get them is modified sine wave. The only bad thing about the Motorola is control knobs are VERY loose and the vhf indicator on the zenith is cracked. That's just quick look at them, I haven't dug into them. Although they both do need cleaned.
